' To all whom z'tmay concem:

Be it known that I, An'rmm L. STAPLES, citizen of the United States, residing at New Haven, in the coun of New Haven, and State of Connecticut, ave invented new and useful Improvements in'Roller-Skate Rolls, of which the following is a specification.

My invention relates toball-bearin skaterolls of the enclosedor so-called military type, and has for its ob'ect to provide a roll which can bemanu actured at a low cost, which shall contain a number of parts, and whichbiv a slight change of proportion may be a apted to contaln either a single or double row of balls.

A further object is to rovide a roll having a truss strengthene support between the rim and the hub suitable or withstanding lateral as well as radial strains incident to-its use on a roller-skate.

In the accompanying drawings, which show the preferred embodiment of my invention,-

Fig. 1 is a sectional view of a roll madein accordance with my invention, and containing a single row of balls;

ig. 2 is a sectional view of a roll made in accordance with my invention, and containing a double row of balls;

Fig. 3 is a side view of a 'skateroll made in accordance with my invention;

Fig. 4 is a view of one of the shouldered rivfiets used to unite the side plates of the r0 Fig. 5 is a sectional view of amodification of my invention, wherein a plain rivet, together with a separate collar or washer is used in place of the shouldered rivet shown in the preceding figures;

Fig. 6 is a detailed view of the collar, and Fig. 7 is a detailed view of the rivet, shown in ig. -5. v

In constructing a roll according to my invention. I employ two similar side plates 10, preferably stamped of sheet metal having integral inwardly-bent rim-forming.

portions 11 with their edges adapted to register evenly in close abutment. These si e plates are exact duplicates of each) other, and therefore may be produced by the same dies. The side plates 10 are further formed with depressed web portions 13 preferabl flat, which are joined to the rim portions y portions 12, preferably inclined .ter case,

inwardly and have outwardly-bent hub portions 19 to form an in ardly concave raceway for the balls 20.

The cooperating raceway for the balls 20 may be formed as shown in the spindle 21 mounted axially within the roll and which may be attached to the skate in-any desired manner. If it is desired to use a single row of balls in the roller, a spindle of the form shown in Fig. 1- may be employed, while if a double row of balls is desired, the form shown in Fig. 2 should be-used. In the latthe hub portions 19 of the plates are adjusted somewhat farther apart, as shown. 7

Various means may be employed to firmly unite the plates together in forming the roll, but I preferably so unite them as to s ace the depressed web portions 13 a art, t ereby lessening the necessity for any s arp bending of the (plates 10, and also so as to obtain a trusse side plates for withstanding lateral and radial strains to which the roller is subjected when in use on roller-skates. .In one embodiment I have. employed shouldered rivets 15 of the form shown in Fig. 4 to fasten the plates 10 together. The enlarged or shouldered ortions 16 of the rivets 15 serve to space t e webs 13 apart and the reduced end portions are received in the openings 14 of the plates for being shown. spaced intervals around the plates have been found to sufiice, as shown in Fig. 3.

Another embodiment of "fastening and separating means for the plates is. shown in Fig. 5, wherein a plain cylindrical rivet 22,

together with a separate collar or washer 23 between the plates. is employed to hold the side plates in assembled position. A threaded stud or other equivalent mechanical element secured to the plates might be used for this purposeif desired, and in some cases the plates might be united to an intervening spacing member by spot-welding or equivalent means.

What 1' claim is,-.

1. A skate roll comprising two-side plates having inwardly bent rim portions abutting in edge-to-edge contact only, intermediate annular web portions disposed in closely adjacent parallel relation, and outwardly bent hub portions, said hub portions having inner concave faces to provide ball construction between the til races, said rim, web and hub portions being integral in each side plate, and means for rigidly securing together said side plates at the parallel web portions thereof.

2. A skate roll comprising two side plates having inwardly bent rim portions abutting in edge-to-edge contact only, intermediate annular web portions disposed in closely adjacent parallel relation, and outwardly bent hub portions, said rim, Web and hub portions being integral in each side plate, means interposed between the web portions of each side plate for spacing apart and stiliening the same, and means for rigidly securing together said side plates and holding said web portions in engagement with said spacing means.

3. A skate roll comprising two side lates having inwardly bent rim portions abutting in edge-to-edge contact only, intermediate annular web Iportions disposed in closely adjacent para lel relation, and outwardly bent hub portions, said rim, web and hub portions being integral in each side plate, rivets rigidly connecting said side plates, and shoulders on said rivets engaging each of said side plates for spacing apart and stiffening the annular web portions thereof.

4. A skate roll comprising two side plates having inwardly bent rim portions abutting in edge-to-edge' contact only, fiat annular portions disposed in closely adjacent parallel relation, web portions inclined inwardly from said rim portions connecting the latter with said flat portions, hubs turned outwardly from said fiat portions and having their inner faces concave to provide ball races, rivets extending through said fiat portions for securing together the side plates, and shoulders on said rivets for engaging each of said flat portions to space the latter apart.

5. In a skate roll the combination of two side plates having integral inwardly bent rim portions, inwardly inclined intermediate portions, fiat annular web portions and inwardly concave ball-race-forming portions with means for rigidly connecting said flat annular web portions of said side plates, the said inwardly bent rim portions abutting against each other with edgeto-edge contact only.

6. In a skate roll the combination of two side plates having integral inwardly bent rim portions, inwardly inclined intermediate portions, flat annular web portions and inwardly concave ball-race-forming portions with means for spacing and rigidly connecting said flat annular web portions of said side plates, the said inwardly bent rim portions abutting against each other with ed e-to-edge contact only.

i In a skate roll the combination of two side plates having integral inwardly bent rim portions, inwardly inclined intermediate portions, fiat annular web portions and inwardly concave ball-race-forming ortions with shouldered rivets for rigidly connecting said fiat annular' web portions of said side plates, the said inwardly bent rim portions abutting against each other with edge-to-edge contact only.

In testimony whereof I have afiixed my signature.
